You have probably seen your nurse insert a syringe into a large vial, extract some liquid, and then leave a substantial amount of vaccine in the original container. If you've witnessed this seemingly benign procedure, you've seen how vaccine manufacturers are saving money at the expense of public health. In order to store larger amounts of vaccine at a lower cost, companies began offering "multi-dose units" while adding preservatives to prevent contaminations. That way doctors can open and close a vaccine container, inviting germs into the once-sterile solution, while assuring the public that those contaminants are quickly killed by the preservative.Sound familiar? It's the same story of corporate America's love affair with preservatives. It saves them money, while posing an undue risk to your health. But like many toxic preservatives found in food, a vaccine preservative kills more than just bacteria and fungi; it can lead to extensive neurological damage in your children, and has even been implicated in autism.
